Elfab's New Rupture Disc Detection System is Ex d-approved

Press release date: January 17, 2014

MUMBAI -- Flo-Tel(TM) XD Represents Another Industry-first for Elfab

Leading rupture disc manufacturer Elfab [ has introduced the industry's first Ex d-approved burst detection system, FloTel(TM) XD.

For over a decade, Flo-Tel(TM) has offered customers across a wide range of industries the unique features of ATEX Zone 1, non-invasive, fail-safe and re-useable detection when using rupture discs.

Working with key customers, Elfab's engineers have sought to offer a more cost-effective system for key applications, such as LNG. Flo-Tel(TM) is now fully Ex d-approved, negating the need for intrinsically safe barriers and interfacing directly with the customer's remote terminal unit, all of which reduces installation costs considerably.

As with all of Elfab's Flo-Tel(TM) products, Flo-Tel(TM) XD is a one-time-only installation unit. The system has no moving parts and is therefore exceptionally reliable. Its method of operation is specifically designed to be fail-safe. Any periodic maintenance checks specified by customers can be carried out by a non-electrically-qualified fitter using the Test-Tel(TM) installation tool.

The Flo-Tel(TM) sensor fits into the rupture disc holder while a magnet is attached to all Elfab rupture disc products. When the disc bursts, the magnet arcs away from the sensor and produces an open circuit signal. After functioning, only the disc needs to be replaced, saving on both costs and downtime.

Elfab's Opti-Gard(TM) range of rupture discs was recently tested to over one million life cycles, a service life more than four times longer than the previous industry-best.
